I'm confusing...??? (about VB6 and VB2008 Serial Communication) please help...

[boyguitar1]

Hello...

Now i'm need to send some command via serial port but I found the issue below.
Example:
1. use VB6

MSComm1.Output = Chr(192) & Chr(38)

and I used program Free Serial Port Monitor check the command.
I can see as " C0 26 " This is correct!!

2. 1. use VB2008

 SerialPort1.Write(Chr(192) & Chr(38))

and also I used program Free Serial Port Monitor check the command.
I can see as " 3F 26 " this not correct!! (0x3F = Chr ? = Dec 63 )
Why ???????


Please help me why not ??? or My code is incorrect ??

I tried to do many code but not work!! for VB2008



Thank in advance
boy...

If you use the SerialPort1.Write method then the argument must be a byte, not a string.

Convert the chr/hex value to a byte.

Can you help give me a example code ?

Hope this code will help

Dim targetNumber(1) As Byte

targetNumber(0) = 192
targetNumber(1) = 38

SerialPort1.Write(targetNumber, 0, targetNumber.Length)
